Resumo: | ABSTRACT The Amazon forest is rich in plant species diversity, among them,Piranhea trifoliata stands out, which is popularly known as piranheira, because their fruits are eaten by fish. Their barks are used as bath composition on uterus inflammation and as tea in malaria treatment. This study aimed to fractionate the dichloromethane and dichloromethane phase from methanolic extract of leaves of Piranhea trifoliata. The leaves were dried, grounded and extracted with dichloromethane, methanol and water. The methanol extract was partitioned with dichloromethane and ethyl acetate. The chromatographic fractionation yielded six pentacyclic triterpenoids: friedelan-3-one, 28-hydroxy-friedelan-3-one, 30-hydroxy-friedelan-3-one, lupeol, α- and β-amyrin mixture, besides the mixture of the steroids: β-sitosterol and stigmasterol. The substances structures were identified by 1H- and13C-Nuclear Magnetic Resonance (NMR) analysis and literature data comparison. This is the first report describing the chemical study of P. trifoliata leaves.
